ALEXANDRE DAMIEN LAGRELLE, OF LOUVRES, FRANCE.

REGULATOR FOR ELECTRIC HEATERS.

SPECIFICATION forming part of Letters Patent No. 573,670, dated December22, 1896. Application filed January 29, 1894. Serial No. 498,281. (Nomodel.) Patented in France November 18,1893,No. 234,155.

To all. whom, it may concern.-

Be it known that I, ALEXANDRE DAMIEN LAGRELLE, a citizen of the FrenchRepublic, and a resident of Louvres, Seine and Oise, in the Republic ofFrance, have invented certain new and useful Improvements in Regulatorsfor Electric Heaters, (for which I have obtained Letters Patent ofFrance, dated November 18, 1893, No. 234,155,) of which the following isa specification.

My invention relates to the construction of water-closet seats andappliances for the communication, by means of electricity, of a certainamount of heat to the same, so as to render such seats more comfortablethan heretofore and to prevent them from giving a sensation of cold.According to the intensity of the current and the less or greaterconductivity of the conductor, that is to say, according to theresistance opposed to the current by the conductor, the greater or lesswill be It will be readily understood that by placing in the circuit ofat current the intensity of which is known a suitable resistance therecan be obtained sufficient heat for warming.

My invention is illustrated in the accompanying drawings, wherein thesame letters of reference refer to the same parts in all the views.

In the drawings, Figure 1 is a central vertical section of aconstruction embodying my invention; Fig. 2, an under side View of thesame, and Fig. 3 an enlarged View of the automatic cut-01f referred tohereinafter.

The seat may be arranged in the usual way and receive either below orabove it the electrical appliances below described and which may vary intheir arrangement and to suit the construction of the seat itself.

I construct the seat of an upper and lower frame, each containing theusual central aperture. Between such frames there is provided a bordermade of wood or other suitable material coming out flush with the innersurfaces of said frames. I also preferably provide an outer bordercoming out flush with the surfaces of said frames, and between theframes and the borders I place the electrical resistance as followsiUpon an ordinary seat A, I

lit the warming-seat A, made preferably of wood. Ihis seat is also bypreference pivoted or hinged to the ordinary seat, so that it can beraised orlowered, as desired. For that purpose it is provided withpivots, which take into bearings A fixed to the ordinary seat.

The conductorcoils are indicated at cl. The number and diameter of saidcoils are such as to obtain the resistance necessary to produce thequantity of heat required for the warming process. Said coils are housedin a recess 6 in the seat, the recess surrounding the centralperforation in the seat, and are placed in a substantially horizontalplane and fixed by means of pegs or staples to the under side of theboard f, which forms the seat.

The automatic switch controlling the eleotrical connection of theresistance is shown in detail in Fig. 3and in proper relation with thecloset-seat in Fig. 2. It comprises expansion-rod it, the length of thefree part of which may be regulated by means of nut 71 The end 7& ofsaid rod 7t" is provided with a stud which acts on the pivotedspring-actuated device m.- Said device, having a slot to receive thestud on the end it can be tilted a short distance without the coactionof the rod and be retained tilted forward or backward by the springmhaving one end attached to the outer end of the pivoted device am. Saiddevice on has adjacent to its pivot two horns m m. The horn m is used totilt one end of a spring-actuated piece a and break the circuit betweenthe terminal 0 and said piece it, to the pivot of which piece at thewarmingwire is connected. Alongside of the device on the spring-actuatedlatch 01 is placed to engage with the hooked end of the piece a andprevent its oscillation, but when the expansion-rod 7t" contracts thehorn m of the device m bears against the long arm of the latch n andreleases the spring-actuated piece at, the circuit being then closed bythe spring of said piece 12-.

The electrical current, generated either by a dynamo-machine or battery,enters the seat A at a, whence it passes to the terminal 0. Then theseat is closed down and is being warmed, the circuit is closed by thespring actuated piece 17.. The final conductor-coil leads to terminal 2,whence the conductor j leads the current out of the apparatus.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with a water-closet seat, an

5 electric resistance-coil (Z attached to the frame of the seat and anautomatic switch controlling the electrical connection of the resistaneeand consisting of an expansionu'od 7.2,

a pivoted spring-actuated piece m adjusted TO to be thrown by said rod,a spring-acti'iated contact-make].- adapted to he thrown out of contactby part m, and a Spllllg-l ttl1ftt0tl latch cooperating with thecontact-inakcr, substantially as set forth.

In witness whereof I have hereunto set my 15 hand in presence of twowitnesses.
